This paper presents an Arduino-based smart meter system to help monitor energy usage in an economic and efficient way. The system is applicable to linear electrical loads, i.e., light bulbs, and gives accurate readings of important parameters such as voltage, current, and apparent power. A unique aspect of this system is that it not only tracks the quantity of electricity consumption but also enables users to control electrical loads remotely using SMS. where users can conveniently control, turn on, and turn off electrical loads, making it a simple and effective method of energy management in real time. In addition, the system has also been field-tested under real-world conditions for performance, reliability, and accuracy, and it works well in a wide variety of applications. The implementation cost is extremely low. Priced at an estimated $60, this design is a low-cost, effective solution that can work both for residential and commercial use. The system’s real-time energy monitoring and remote-control functionality will meet the growing need for intelligent energy consumption analysis and efficiency solutions. The proposed system is effective, where electrical load monitoring and control are conveniently achieved through the utilization of Arduino technology. Feasibility, scalability, and cost-efficiency is what it is all about. This study shows how essential most intelligent solutions are in electricity management today. These results directly exemplifies how this system supports a sustainable power use by giving users more power over their power use, reducing power waste and finally enhancing the efficiency of power utilization.
